Role names and user ids

Hello, We have Online Workgroup Server 7.12.TC3 running on a Windows NT 4.0 server. I am trying to set up a few new roles with the "CREATE ROLE" statement and I'm having a problem creating a particular role. I would like to create a role called VIEWONLY. However, I didn't realize that you can't have a role with the same name as a login id. I had already created an NT user with the login id VIEWONLY. I had also logged into Informix at least once as VIEWONLY. After I realized that I couldn't have a role with the same name as a login id, I deleted the VIEWONLY user from NT. However, Informix must still think that it exists because I still get the same error when I try to add it. The error messages is: "SQL Error (-19800): Role name already exists as a user or role." I could not find this error in the Find Error utility. I ran a few tests and it seems like Informix is storing the login ids of everyone who has logged in and is checking that list for conflicts when setting up a role. For example, I can create an NT user called "ABC" and still create a role called "ABC". It is not until I have actually logged into Informix as ABC when I start having a problem. After I have logged in as ABC and then logged out and killed the NT user ABC, I cannot create a role called ABC. Informix still thinks that the user exists. Does Informix store these login ids in some system table where I can delete the non-existant VIEWONLY user? Just to let you know, I would normally give up and choose a different name besides VIEWONLY, but that is not practical in this situation. Thanks for any help, Jay Sullivan.
